Alstroemeria plant named ‘Zalsachablu’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Zalsachablu’, characterized by its erect and moderately strong flowering stems; moderately vigorous growth habit; upright inflorescences with relatively small white to light green and light red-colored flowers without stripes; excellent postproduction longevity; and relative tolerance to high temperatures.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘ZALSACHABLU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a cut flower Alstroemeria, and hereinafter referred to by the name ‘Zalsachablu’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Rijsenhout, The Netherlands. The objective of the breeding program is to create new cut flower Alstroemeria plants with desirable flower and plant qualities, attractive and unique flower coloration and excellent postproduction longevity.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in Rijsenhout, The Netherlands in May, 2011 of a proprietary Alstroemeria hybrida selection identified as code number 9142-5, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number 7469-1, not patented, as the male, or pollen, parent. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rijsenhout, The Netherlands in June, 2012.

Asexual reproduction of the new Alstroemeria plant by rhizome divisions in a controlled greenhouse environment in Rijsenhout, The Netherlands since September, 2012 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zalsachablu’. These characteristics in combination distinguish ‘Zalsachablu’ as a new and distinct Alstroemeria plant:

-   -   1. Erect and moderately strong flowering stems.     -   2. Moderately vigorous growth habit.     -   3. Upright inflorescences with relatively small white to light         green and light red-colored flowers without stripes.     -   4. Excellent postproduction longevity.     -   5. Relatively tolerant to high temperatures.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ from plants of the female parent selection primarily in flower size and color as plants of the female parent selection have larger pink-colored flowers. In addition, flowers of plants of the new Alstroemeria do not have developed reproductive organs whereas flowers of plants of the female parent selection have fully-developed stamens and pistils.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ from plants of the male parent selection primarily in flower size and color as plants of the male parent selection have larger yellow-colored flowers. In addition, flowers of plants of the new Alstroemeria do not have developed reproductive organs whereas flowers of plants of the male parent selection have fully-developed stamens and pistils.

Plants of the new Alstroemeria can be compared to plants of Alstroemeria hybrida ‘Zalsabri’, disclosed in U.S. Plant Pat. No. 25,213. In side-by-side comparisons, plants of the new Alstroemeria differ primarily from plants of ‘Zalsabri’ in the following characteristics:

-   -   1. Flowers of plants of the new Alstroemeria and ‘Zalsabri’         differ in flower color as plants of ‘Zalsabri’ have pink-colored         flowers.     -   2. Flowers of plants of the new Alstroemeria do not have stripes         whereas flowers of plants of ‘Zalsabri’ have stripes.
